Application filed August 8,1921. Serial No. 490,592..

1 '0 all whom it may concern-i I Be it lQ'lOWll that I, E. a citizen of the limited Statesresidine at Philadelphia. in the county of Philazlelphia and l ennsylvania, have inventi-ul an Improved l lleetrie Conductor Support, of which the tellmvinsr is a specification.

y invention relates to electric conductor supportsadapted to be :oplied to the tops of poles or the lime. and Aisprimary objects are to provide-an'improved device oi simple,- strong and e'llicient constru tion th; nhe produced at relatively small cost and can he applied with facility, with avoidance of defeats common to prior constructions. I

lleretoforedevices of this character have required special forging of the m porting: member or members. the cr the pole to fit the parts of the device thereite oi to. theboring of numerous holes in the pole proper, the use of parts of such hull: as to be objectionable in shipping. and the use of a pole with its top substantially flush. with the top of the supporting device.

The improvements of my device are such hat only two bolts are necessary for securing: it to the pole. no Forgings are required. the parts can he knocked down in compact form tor hipping. and the finished construction is ri f l. lends itself to corner'turning and has the requisite design for resisting the V in various directions to whichit is subjected. The device combines. maximum strength with minimum weight, provides for incorrect drilling of the pole. and avoids the necessity for cutting; the pole to fit the structure thereto. The means to which the wire or conductor iittin rs are attachedv bear such to pole in the operative position; Fig. 2

is a plan view of the same; and Fig. '3 is a top view of the upright angle bar on the line 3 -3 of Fig. 1. e I

The support, in the form thereof here sewhich passes therothrou 'h.

lected for the purpose of illustrating the in vention, comprises the angle iron cross arm or beam 1, which is preferably straight, and to which .is detaehahly connected the 1113-: r5 T4; ai iron 1' strut 2, 1y means of the ii at iron gusset the latter connected to a leg; thereof. hythejbolts or rivets 3' and to the transverse parallel leg of the member I The top of the u le bar is l'by the bolt U 2 has its unper end cut ollef: right angles to its length and the projecting free end of the complementary legvbent at right angles'in bee I relation therewith. to provide a healing"? in which is formed a bolt hole 2.. The parallel vertical legs 1 and 9. are

fixed to thetop or" thepole 4 by the respee tiv-e bolts 5 and 6, the former passing through the gusset 3 and the latter through a longitudinal slot 2 in the web engaging the post to avoid the necessity for accuracy in spacii the two holes bored in the post for making the connections. The slot 2 can be termed at the desired distance below the top of the member 2 for extending the latter the desired distance above the top of the pole and supplementing; the length thereof. i V

A yoke 7 (it strap iron'h'as its nub-dim: section fixed to the poled. on the opposite side thereof from the member 1. by the bolt 5 The yoke 7 bent to the "term of a symmetrical bow and has its ends lined to therespective ends oitbe men. ir-r l by the bolts 8 passingrthe vertical of such member. I

Theeross arm 1 has synnnetrically positioned on its horizontal web the insulators i), secured by the bolts 10., and the vertical. member 2 has the insulator ll secured on.

the bearing 2 by the bolt 12. the arrange- Jnent'distrilniiiiuz the load from the wires symmetrically.

As the members 1 2 and 3 lie in a plane they can be attached to. the pole readily without fitting or cutting, can be handled or shipped readilyin assembled relation or can be shipped in. dissociated relation and readily assembled. The strap 7 can be shipped in its straight form and readily sprung to shape to place it in its assembled relation, where it combines with the member 1 to form a truss adapted for resisting the stresses to which it 'may be subjected by forces acting in various directions. The member 2 has the advantage of carrying its norin'al vertical load by leugitui'linal compression therein and the an 'ularly disposed \VQllS provide desiru'l resistance to lateral stresses.

Having described my invention, I claim 1. In an electric coi'uluetor support, the cen'iliination with a cross arm, of an ins11- later support comprising; a strut iixed in transverse relation to and projecting above d arm, and a yoke having its ends fixed l said arm on opposite sides of said strut.

2. In an electric conductor s n'iort, the con'ili natimi with a cross arm, of an up right, a gusset for fixing said u 'n'ight to said cress-arn1, and a yoke having its ends fixed to said mess-aria on opposite sides 01 said gusset.

3'. In an electric conductor support the combination with an angle iron cross arm, of an angle iron stri'it i'ised approximately at right angles thereto at its median section, said arm and strut having legs that are approximately parallel. and a yoke having its ends fixed to arm on eppes '9 sides of said sl'rut said yoke bowed appri'lximal'ely at right angles to the lengurtli ol' said strut.

l. In an electrie conductor support, the combination with a cross arm, of an up right lixed l'l'ierete and adapted to lie against a pole in approximately arallcl relation thereto, said supportliaving liolt holes therein for fixing it to a pole and permitting; the eCljusuii'ient oil the distance bet *een bolts passing therethrougli.

5. In an electric conductor su n iorl, an iron cross-arm liavinga vertical leg: and a horizontal leg adapted 'l'or supporting insulators and 'lixed to said illlll illl angle iron strut having; a leg approxiuia ely parallel to said vertical leg and a leg: approxiinalely at llgg'lll? angles thereto, said slrut having llie upper end 01 one of its legs removed and the upper end ole iis other leg bent inwardly upon the complementary leg to provide an insulator bearing.

In testimony. whereof I have hereunto set my name this H1 day of Jrugnst, 1921.
